Oak Grove Airport - Ghost Field
Established around 1962-63, Oak Grove Airport was built and operated by aviation pioneer Maurice Hunter "Pappy" Spinks, a renowned aerobatic competitor and aviation manufacturer. Described by fellow aerobatic pilots as a "rough edged old millionaire," Spinks made a fortune during the Vietnam war manufacturing skids for Bell Helicopter's Huey helicopters at a facility located on the airfield.
In the early days, Oak Grove had several hangars, with a flight school, aircraft sales, maintenance, stores, and manager all crammed in a single building, but the airport expanded rapidly. By 1966, nicely renovated surplus barracks housed the flight school. A rotorcraft flight school, charter operation, and second helicopter operation soon joined other businesses on the field. Bell Helicopter sent customers' pilots from around the world to Oak Grove for FAA certification and additional ratings.
The airport hosted the National Aerobatic Championships from 1967-71, bringing out the giants of aerobatics and aviation, including Poncho Barnes, Allen Bean, Charlie Hillard, and Harold Krier. The Spinks Aircraft Industries building was built in 1968 specifically for the construction of the Spinks Acromaster, which placed 3rd in the 1970 World Aerobatic Championships. In 1970, Pappy Spinks completed a terminal and administrative building along with additional hangars, including one dedicated to his aircraft collection.
Oak Grove reportedly faded away after Pappy Spinks died. On May 28, 1989, a ceremony was held closing Oak Grove and activating Spinks Airport, adjacent to the west and named in his honor.
The airport began with a 2,000-foot turf runway. By 1970, it had a 3,050-foot asphalt runway which, by 1978, had been paved and lengthened to 3,500 feet. The concrete runway 17/35 still exists, in very good condition, and is what you will use to access this cache. Some of the old hangars are still used by aircraft operating from Spinks Airport, with a taxiway connecting them to the Spinks runway. Come and see what's left of Oak Grove while you can. Last I heard, the City of Fort Worth was planning to convert the old runway into an east-side access road to Spinks Airport.
To get to the cache, enter from Rendon-Crowley Road (Hwy. 1187) apx. 1/2 mile east of I-35, at N 32° 34.787 W 97° 17.999. Veer left onto old runway 17. Head south on the runway. On your right you'll see what's left of Pappy Spinks' old house. Park at the end of the runway and make a short walk to the cache. (Since the first container disappeared, the replacement is somewhat attached in place. Please just remove the lid.) Watch you step! There is an almost invisible "trip wire" looping out of the ground at one spot on the "road" between parking and the cache!
